Encounters with God in Brazil

The stories in this book are about real people, known personally to the author, during more than years of missionary service in Brazil. He tells movingly of the loss of his first two children and the miraculous healing of a sick child in the Amazon rainforest and of a young man cured of cancer, having been given two years to live by the doctors. In this book, the author describes how he was hit by a car and held at gunpoint in his own home.
Why does God respond to some prayers and apparently not others? Where is he to be found? For those who feel that God's intervention in human affairs can be explained as mere coincidence, these stories challenge that assumption.
